Overview specification

NP-2106 (single-axial) and NP-2506 (tri-axial) piezoelectric type accelerometers feature ultra compact and light weighted, suitable for the drop impact tests of mobile device or portable product and vibration measurements of light weighted parts.

The NP-2106 is super light weighted type weighing mere 0.2g and allows measurement of ultra high acceleration maximum at 100,000 m/s². The tri-axial accelerometer NP-2506 can measure the acceleration of three directions (X, Y and Z). It is the size of 8 x 7 x 5.5 mm and weighs 1.2g, which is remarkable compact size for the tri-axial accelerometer. These accelerometers are suitable for the drop impact tests of mobile device or portable product and vibration measurements of light weighted parts offering versatile applications.

Features

Ultra high acceleration can be measured maximum at 100,000 m/s²(NP-2106)/25,000 m/s²(NP-2506).
Super light weighing of 0.2 g (NP-2106)/1.2 g (NP-2506) minimizes the influence of vibration mode to the measurement object.
Thanks to the ultra compact size of φ3.5×2.5 mm(NP-2106)/8×7×5.5 mm(NP-2506), it is easy to mount on small space or small measurement object.
They are charge output type accelerometers and have wide dynamic range.

System configurations

Applications

Example of the an impact test of mobile products or electronic printed wiring board

The impact acceleration at the time of dropping products can be measured by mounting the sensor on the mobile devices.

They can measure the vibration of parts which are installed into the small space such as assembled parts in an automobile or printing mechanism section in a printer.

It can be used as sensor for monitoring the acceleration of metallic processing machines such as

press or impact machines. The vibration measurement of light weighted parts such as a thin pipe of heat exchanger or a small driving part.
